Abstract

The invention relates to the technical field of linear switched reluctance motor control, in particular to a force control method and a force control system of a linear switched reluctance motor. The method comprises the steps that in the process that the linear switched reluctance motor approaches a machining target, obtaining the actual position, speed and current of the linear switched reluctance motor; judging whether the linear switched reluctance motor reaches or exceeds a preset contact condition according to the actual position and the speed condition; when the judgment result is yes, indicating that the linear switched reluctance motor is in contact with the target; and after the linear switched reluctance motor is in contact with the target, limiting the output force of the linear switched reluctance motor according to the output strategy, and then controlling the output of the force. According to the force control method and system of the linear switched reluctance motor, after the linear switched reluctance motor reaches the contact condition, the linear switched reluctance motor enters the force control mode, and the output force is limited by limiting the output current of the motor, so that the output force of the motor and the target is stable, and the force control effect is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of linear switched reluctance motor control, in particular to a force control method and a force control system of a linear switched reluctance motor. 【Background technique】 [0002] The linear switched reluctance motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. Widely used in modern processing industries, such as laser cutting, high-speed grinding machines, precision lathes, machining centers, etc., all require high-precision linear motion. [0003] The external output of the linear switched reluctance motor is mainly thrust. Due to the theory, design, manufacture, load and interference of the linear switched reluctance motor, there are thrust fluctuations in the linear switched reluctance motor. [0004] The linear switched reluctance motors in the prior art generally switch hard through position / f...
